Background Lumbar facet nerve (medial branch) block for pain relief in facet syndrome is currently performed under fluoroscopic or computed tomography scan guidance. In this three-part study, the authors developed a new ultrasound-guided methodology, described the necessary landmarks and views, assessed ultrasound-derived distances, and tested the clinical feasibility. Methods (1) A paravertebral cross-axis view and long-axis view were defined under high-resolution ultrasound (15 MHz). Three needles were guided to the target point at L3-L5 in a fresh, nonembalmed cadaver under ultrasound (2-6 MHz) and were subsequently traced by means of dissection. (2) The lumbar regions of 20 volunteers (9 women, 11 men; median age, 36 yr [23-67 yr]; median body mass index, 23 kg/m2 [19-36 kg/m2]) were studied with ultrasound (3.5 MHz) to assess visibility of landmarks and relevant distances at L3-L5 in a total of 240 views. (3) Twenty-eight ultrasound-guided blocks were performed in five patients (two women, three men; median age, 51 yr [31-68 yr]) and controlled under fluoroscopy. Results In the cadaver, needle positions were correct as revealed by dissection at all three levels. In the volunteers, ultrasound landmarks were delineated as good in 19 and of sufficient quality in one (body mass index, 36 kg/m2). Skin-target distances increased from L3 to L5, reaching statistical significance (*, **P < 0.05) between these levels on both sides: L3r, 45+/-6 mm*; L4r, 48+/-7 mm; L5r, 50+/-6 mm*; L3l, 44+/-5 mm**; L4l, 47+/-6 mm; L5l, 50+/-6 mm**. In patients, 25 of 28 ultrasound-guided needles were placed accurately, with the remaining three closer than 5 mm to the radiologically defined target point. Conclusion Ultrasound guidance seems to be a promising new technique with clinical relevance and the potential to increase practicability while avoiding radiation in lumbar facet nerve block.

Background: This work was intended to distinguish the results of Percutaneous Nephrolithotomy (PCNL) related to stone-free rates (SFR) by the varying body mass index (BMI) of the patients who subjected for lower calyx stone treatment (with a stone range of ≥2 cm). Materials and methods:Atotal of 287 patients who went through the PCNLfor kidney stones were selected for the study. Only patients treated at Shahid-Ghazi Hariri Surgical Specialties Hospital (Medical City) and Al-Qima Private Hospital (Baghdad) within the time frame of January 2015 to April 2018 selected for the study. Information on patients' BMI and SFR was collected and analyzed to compare and contrast the differences in obese patients. Results: The average age and BMI of the patients are 41 years old and 34kg/m2 respectively. For total mean stone size 2.2 cm. Besides that, the average value for height was 173cm and weight 101kg. The overall stone-free rate was 82% and the mean hospital stay was 115±51.21 min, Major complications were seen in 65 patients (22.6%). No statistically significant differences were found in SFR, age and stone side among the four groups. The stone-free rates (SFRs) of a single procedure for the groups were 85%, 79.3%, 79%, and 84%, respectively. Major complications were not observed either during or after the operations. Conclusion: The effectiveness of PCNLtreatment for removal of lower calyceal stone is influenced by the varying patients' BMI value and results in high SFR value.
